My trans just went in my ''94 Silverado 2500 AT w/4x4 & 5.7 engine. I needed a truck fast so bought a ''93 Chevy Cheyenne 2500 AT w/4x4 & 5.7 engine. The ''93 needs A LOT for inspection-more than I''m willing to put into it since the frame has a little rot in the rear and the body is not in great shape. Also, there is a grinding noise coming from the differential. I would like to swap the trans from the ''93 and put it in the ''94 because the ''93 has a rebuilt tranny in it and I know it''s good because I drove it. The problem is that the ''93 is a Heavy Duty truck with the 17 bolt pan. The ''94 has the 16 bolt pan. So I am willing to pull the engine & Trans out of the ''93 and put in the ''94, but will it work?? I believe that the tranny shifts thru the computer since there is a green plug on the pass side on the top of the tranny pan. But on the ''94, the same plug is on the driver side on the side of the tranny pan. Do I need to switch computers to make this swap work?? Is it possible to do this job? Any advice would be greatly appreciated since I would like to change it out this weekend.
Thanks!
